Nanotribology

The research projects developed in the field of nanotribology at the lab are described below:

The study of the wear mechanism in boron carbide (B4C) thin films induced by the energy dissipation at the interface of two surfaces while in contact and in relative motion - in this project the relationship between friction and wear of boron carbide thin films is studied, as well as the energy transfer mechanism at the interface between the AFM tip and the surface of the films on the formation of a low lubricant layer at the films surface.

The study of the bombardment of amorphous carbon films by Ge ions - in this project the AFM is used to determine the amount of Ge atoms at the upper most layer of the films by means of the friction coefficient and surface morphology. The amount of Ge atoms can be estimated via a comparison of the friction of pure carbon, pure Ge and the bombarded films surface.
